The present study examined the influence of momentum sequence (positive vs. negative) and environmental climate (hot–wet vs. neutral) on supporters’ (i.e. virtual observers’) reported levels of perceived psychological momentum (PM) during a simulated cycling competition. Participants supported one of two competing cyclists involved in a race that was displayed on a screen in a lecture hall. The race scenario was manipulated so that the supported cyclist appeared to undergo either a positive or negative momentum sequence. In addition, participants were either exposed to a hot–wet environmental climate or to a neutral environmental climate while observing the race scenario. According to the results, reported levels of PM were higher in the positive momentum sequence condition than in the negative momentum sequence condition, consistent with the notion that supporters’ PM is influenced by a positivity bias, and reported levels of PM were also found to be higher in the hot–wet climate condition than in the neutral climate condition, consistent with the notion that environmental climate is a contextual factor that influences PM through the operation of a causal augmenting mechanism.  相似文献   

The influence of shoe drop on the kinematics and kinetics of children tennis players

This study investigated the immediate effects of reducing the shoe drop (i.e. the difference between the heel and the forefoot height) on the kinematics and kinetics of the lower extremities of children tennis players performing a tennis-specific movement. Thirteen children tennis players performed a series of simulated open stance forehands wearing 3 pairs of shoes differing only in the drop: 0 (D0), 6 (D6) and the control condition of 12?mm (D12). Two embedded forceplates and a motion capture system were used to analyse the ground reaction forces and ankle and knee joint angles and moments of the leading lower limb. In D6 compared with D12, the peak impact force was reduced by 24% (p?=?.004) and the ankle was less dorsiflexed at foot strike (p?=?.037). In D0 compared with D12, the peak impact force was reduced by 17% (p?=?.049), the ankle was less dorsiflexed at foot strike (p?=?.045) and the knee was more flexed at foot strike (p?=?.007). In addition, 4 out of 13 participants (31%) presented a forefoot strike pattern for some of the trials in D0. No difference was observed across shoe conditions for the peak knee extensor moment (p?=?.658) or the peak ankle plantarflexor moment (p?=?.071). The results provide preliminary data supporting the hypothesis that for children tennis players, using a 6-mm lower shoe drop might reduce heel impact forces and thus limit potentially impact-related injuries.  相似文献

Competence-based blended learning in building automation: towards a EU curriculum in ‘Domotica’     

L. Sommaruga  E. De Angelis 《European Journal of Engineering Education》2007,32(6):675-685

A competence-based approach was applied to a blended learning on line distance training in the Euroinno EU project aimed at vocational training in building automation. The current paper describes the experience gathered during the learning process and the definition of the curriculum. A number of issues emerged during the sessions concerning regional differences among the various European partners involved in the learning. Refusal to accept e-learning approaches has been considerable among teachers and students in piloting building automation courses, and mainly related to four factors in the tradition of adult education: curriculum tradition, oral tradition, lack of confidence in technical solutions to educational matters and lack of experience with the media.  相似文献

朱元璋驭宦之析   总被引：1，自引：0，他引：1  

王德金 《天津师范大学学报(社会科学版)》2001,(6):39-43

历代史家在谈及明太祖朱元璋严驭宦官时，皆赞誉有加，认为明代重用宦官源于成祖朱棣，与朱元璋毫无干系；其实不然，明代宦官擅权的祸根在太祖，朱棣不过是“萧作曹随”而已。宦官出使、监军、干预经济、刺臣民隐事监觞于洪武年间，它是封建君主专制制度的产物，并不以朱元璋个人意志为转移。  相似文献

朝鲜语母语学习者趋向补语习得情况分析--基于汉语中介语语料库的研究   总被引：8，自引：1，他引：8  

杨德峰 《暨南大学华文学院学报》2003,(4):20-31

本以汉语中介语语料库中母语为朝鲜语的学生使用的带趋向补语的句子为样本,考察了这些学生习得趋向补语的情况,分析了影响他们习得趋向补语的因素。章发现,这些学生习得趋向补语出现的错误既受语际负迁移的影响,也受语内负迁移的影响。  相似文献
